TECHNOLOGICAL FIELD

The present disclosure relates to a compact case. More particularly, thepresent disclosure relates to a compact case in which a sealing memberopening/closing an upper end of a contents storage part is coupled withscrews to a contents storage part, such that an open upper end of thecontents storage part can be sealed by the screw combination of thecontents storage part and the sealing member when a lower case isrotated, and thereby, it is possible not only to improve the internalairtightness of the contents storage portion but also to prevent leakageof contents during the decompression process.

BACKGROUND

Generally, a compact case refers to an article that stores colorcosmetics or powder used for facial makeup for women to easily carry.

The compact cases are being provided in various shapes, and storecontents of power or color cosmetics regardless of their shape. Whenusing a compact case, a user pressurizes a button provided on the frontsurface portion of the container body to open the external cover fromthe container body by hinge pivoting, and applies cosmetics for facialmakeup using cosmetic tools such as a puff or a brush contained in thecontainer body.

Conventional compact cases as in the above are configured to maintaininternal airtightness by covering the upper end portion of the contentstorage part by means of an inner cap. In this case, it is possible toblock air from entering the ins to a certain extent, but internalairtightness cannot be perfectly maintained due to a structurallimitation.

Recently, “a compact container, which is configured to contain anddischarge liquid contents in/out of the compact case while blocking theinflow of air, is disclosed in Korean Patent No. 10-1333044.

The registered patent is characterized to comprise a lower case,receiving a contents storage part where contents are stored, and forminga guide protrusion at an inner lower end thereof to raise/lower acontents storage part; a middle case rotatably coupled at an upperportion of the lower case; a contents storage part storing contents andreceived to the lower case, and forming a rotation protrusion movingalong the guide protrusion; a rotation body mounted on an upper portionof the middle case, interlocked and rotated together when the middlecase rotates, and guiding a vertical movement of the contents storagepart; a sealing member coupled with screws to one side of the rotationbody to open/close an upper end of the rotation body; and an upper casehinge-coupled to one side of the middle case, and rotating to one sideor the other side direction by pressurization of a user and rotatingtogether with the middle case.

The registered patent is configured in a way that when a rotation bodyrotates, a contents storage part rotates together by anascending/descending protrusion of the contents storage part which isinserted to a guide groove of the rotation body, and when the contentsstorage part rotates, a rotation protrusion formed at a lower end of thecontents storage part moves along on a sloped surface of the guideprotrusion of a lower case. Therefore, the contents storage part ascendsand thereby an upper end of the contents storage part is sealed by asealing part of a sealing member.

However, the above-mentioned registered patent has a complicatedstructure for the airtight property, which incurs a problem ofincreasing in manufacturing time and cost.

Meanwhile, recently there has been an increasing tendency to accommodatethe urethane foam impregnated with liquid contents in the interior, andalso various sealing structures are being developed in order to solvethe problem that contents stored in a contents storage part are leakedduring a decompression test due to the limitation of sealing structures.

Meanwhile, at the lower case 100 is provided a first protrusion part 140which meets a first rotation-limiting protrusion 230 and limits rotationof the lower case 100 in a rotational process thereof, and the firstprotrusion part 140 is preferably configured to be in pair whichprotrude to be faced each other as illustrated in FIG. 1.

The middle case 200, made of shape of a ring and rotatably coupled to anupper portion of the lower case 100, is provided with a hinge part 210such that a sealing member 400 and an upper case 500 can behinge-coupled at an upper end thereof and swiveled upwards anddownwards, and further provided with a penetration groove 220 such thatan opening/closing protrusion 520 of the upper case 500 can bepenetrated.

In the described embodiments, it is characterized to be provided with afirst and a second rotation-limiting protrusion 230, 240 at an innerside of the middle case 200 so as to limit the rotational range of thelower case 100 and the contents storage part 300. The first and thesecond rotation-limiting protrusions 230, 240, which are placed in theabove and the below, respectively limits the rotational range of thelower case 100 and the contents storage part 300, and are configured tobe preferably in pair which are formed with protrusion so as tocorrespond each other inside the middle case 200.

The contents storage part 300, coupled to an inner side of the lowercase 100 and storing a contents absorption member 700 impregnated withliquid contents, is provided with a coupling groove 320 which is coupledwith a coupling protrusion 110 of the lower case 100 at an outercircumferential surface thereof such that the contents storage part 300can be coupled to an inner side of the lower case 100.

The contents absorption member 700 which is stored in the contentsstorage part 300 can be made of various materials such as puff, sponge,foam, and brush where liquid contents are impregnated, and preferablymade of porous material which easily absorbs liquid contents.

Furthermore, at an inner side of the contents storage part 300 isprovided a fixation tube 800 which encases the contents absorptionmember 700 so as to fix the contents absorption member 700, and at anupper portion of the fixation tube 800 is provided a fixation protrusion810 to an inward direction such that the fixation protrusion 810supports an upper end of the contents absorption member 700 and therebyprevents the contents absorption member 700 from being separated fromthe contents storage part 300.

In the described embodiments, it is characterized in that at an outercircumferential surface of the contents storage part 300 is provided afirst screw thread 310 for being screw-coupled with the sealing member400. As the contents storage part 300 interlocked with the lower case100 rotates when rotating the lower case 100, the first screw thread 310and a second screw thread 430 of the sealing 400 get screw-coupled, andperform a sealing process through a screw-coupling, thereby effectivelypreventing the contents stored in the contents storage part 300 frombeing leaked in a process of decompression.

Meanwhile, at an outer circumferential surface of the contents storagepart 300 is provided a pair of second protrusion part 330 which meetsecond rotation-limiting protrusions 240 and limit the rotation of thecontents storage part 300 during a rotation process by the rotation ofthe lower case 100, as illustrated in FIGS. 5A and 5B.

Meanwhile, as illustrated in FIGS. 9A to 9C, when all the contents,which are impregnated in the contents absorption member 700 stored inthe contents storage part 300, are used up, it is possible to exchangethe contents absorption member 700. In this case, it is possible easilyto exchange the contents absorption member 700′, by separating thecontents storage part 300 from the lower case 100 in a state ofswiveling the sealing member 400 upwards, and then by coupling withcombined-fit the contents storage part 300 which stores a new contentsstorage part 700′ impregnated with liquid contents.

As in the above, when the exchange of the contents absorption member 700is complete, it is possible to use the contents impregnated in thecontents absorption member 700′ after a sealing tape (S) which isattached on an upper end of the contents storage part 300 to prevent theevaporation of the contents impregnated in the contents absorptionmember 700′.

The sealing member 400 is hinge-coupled to the middle case 200 toopen/close the open upper end of the contents storage part 300, whereina handle part 410 is provided at a front surface thereof for easycontrolling when swiveling upwards and downwards according to the hingecombination, and a reception groove 420 is provided at an upper portionthereof such that a contents application member 900 such as puff can bereceived therein.

In the described embodiments, it is characterized in that at an innercircumferential surface of the sealing member 400 is provided a secondscrew thread 430 which is screw-coupled with the first screw thread 310of the contents storage part 300. As illustrated in the above, since asealing process is performed by closing the open upper end of thecontent storage part 300 by means of the screw combination, it ispossible to effectively prevent the contents stored in the contentsstorage part 300 from being leaked in a process of decompression.

The upper case 500, which encases the contents application member 900and is hinge-coupled to the middle case 200 for being able to beswiveled upwards and downwards, allows the contents application member900 to be used when swiveled upwards to be opened, and protects thecontents application member 900 from external impact and also preventsforeign substance from entering a reception groove 420 when swiveleddownwards to be closed. In addition, it is preferable that a mirror 510is installed at an inner side of the upper case 500 for a user to checkher make-up area when applying contents on her face.

In the described embodiments, it is characterized in that at a frontsurface of the upper case 500 is provided an opening/closing protrusion520 which controls opening/closing of the upper case 500. Theopening/closing protrusion 520, as illustrated in FIGS. 4A and 4B, issupported by a protrusion 630 of a support 600 in a normal state andprevents the upper case 500 from being opened. Then, when broken awayfrom the protrusion 630 by the rotation of the upper case 500 and placedin a guide groove 640, the opening/closing protrusion 520 allows theupper case 500 to open.

The support 600 is made of a ring shape which is coupled to an innerside of the lower case 100 and rotates together by rotation of the lowercase 100. At an outer circumferential surface of the support body 600,as illustrated in FIG. 6, is provided an insertion protrusion 610 whichis inserted to an insertion groove 120 of the lower case 100 for beingable to rotate together according to rotation of the lower case 100.

Furthermore, at an outer side of the support body 600 is provided aseparation-preventing protrusion 620 which is inserted to aseparation-preventing groove 130 of the lower case 100 such that thesupport body 600 is prevented from moving upwards and being separatedfrom the lower case 100.

Meanwhile, at an outer circumferential surface of the support body 600is provided a protrusion 630 which supports the opening/closingprotrusion 520 of the upper case 500 and prevents the upward swivelingof the upper case 500, wherein at a dead end of the protrusion 630 isprovided a guide groove 640 which guides an upward swiveling of theupper case 500.

Hereinafter, referring to FIGS. 7A, 7B, 8A, and 8B, a method of using acompact case according to an exemplary embodiment will be described.

First, as illustrated in FIGS. 7A and 7B, when the lower case 100 isrotated to one side direction in a state of grabbing the upper case 500,the contents storage part 300 which is interlocked with the lower case100 rotates together. Due to this, the first screw thread 310 of thecontents storage part 300 and the second screw thread 430 of the sealingmember 400 are released from the screw-combination and thereby thesealing member 400 ascends in a narrow range.

At this, the lower case 100, as illustrated in FIGS. 5A and 5B, rotatesup to the point where the first protrusion part 140 meets the firstrotation-limiting protrusion 230.

As in the above, when the first screw thread 310 of the contents storagepart 300 and the second screw thread 430 of the sealing member 400 arereleased from the screw-combination, a user swivels in an upwarddirection, and opens the upper case 500 and the sealing member 400 inorder, and as illustrated in FIGS. 8A and 8B, can smear the contentsimpregnated in the contents absorption member 700 by means of thecontents application member 900 and apply onto her face.

Next, after completing application of contents by means of the contentsapplication member 900, a user swivels the sealing member 400 to adownward direction and receives the contents application member 900 inthe reception groove 420, and then swivels the upper case 500 to anupward direction.

As described in the above, if the lower case 100 is rotated to the otherdirection after grabbing the upper case 500 in a state of swiveling theupper case to a downward direction, as the contents storage part 300interlocked with the lower case 100 rotates together, the first screwthread 310 of the contents storage part 300 and the second screw thread430 of the sealing member 400 get screw-coupled and make the sealingmember 400 descend in a narrow range. Due to this, the sealing processis performed in accordance with the closing of the open upper end of thecontents storage part 300 by the sealing member 400.

In the contemplated embodiments, as described above, as the open upperend of the contents storage part 300 gets closed by a sealing structureby means of a screw combination of the contents storage part 300 and thesealing member 400, it is possible to effectively prevent the leakage ofcontents.
